States move to fight 'designer babies' trend

For years, it was unthinkable that society would tolerate so-called designer babies or the move toward gender-based abortion. Now, evidence shows some U.S. couples are making that choice.

In some cases, cultural attitudes are a factor. An analysis of the 2000 Census shows that families of Chinese, Korean, and Indian descent are more likely to have a boy if their first child is a girl  and even more likely if their first two children are girls.
